Shale oil is a source of liquid fuels similar to those obtained from petroleum. Shale oil and petroleum, however, differ enough that both cannot be analyzed by the sume procedure. Hence, when the research program of the Bureau of Mines in oil-shale technology required that an analytical method for crude shale oil be devised, the standard method used by the Bureau for analyzing crude petroleum provided a logical starting point and was modified to make it applicable to shale oil. The distillation equipment and analytical procedure that were developed for crude shale oil and the analyses of 20 oils from foreign and domestic shales were reported in a previous paper. A brief description of the analyti.cal method follows. The oil sample is dried, and determinations of specific gravity, nitrogen and sulfur contents, pour point, and viscosity are made. The sample is separated by distillation into 14 distillate fractions and a residue. The fractions include 7 taken at a distillation pressure of 760 mm. of mercury and 7 taken under vacuum at 40 mm. Volume and specific gravity are determined on each fraction, aniline point on each vacuum fraction, and kinematic viscosities on fractions 11-14. The distillate fractions are composited into three blends consisting of fractions 1-7, 8-10, and ll-14. These and the distillation bottoms are designated as naphtha, light distillate, heavy distillate, and residuum, respectively. These four major fractions were analyzed for nitrogen content, carbon residue and ash of the residuum, tar acids and bases by analytical extractions of the naphtha and light distillate, and hydrocarbon types in the extracted fractions. Properties that are calculated from determined values are yield in volume- percent of each fraction and blend, specific gravity of each blend, and carbon residue and ash of the crude oil.
